Coronary Artery Fistula -- Child

Definition

Coronary artery fistula is an abnormal connection between the coronary artery and the heart or other blood vessels. Coronary arteries carry oxygen-rich blood to the heart tissue. A small fistula will not affect this blood flow, but larger fistulas may cause problems.
